FIG. 1 is a schematic block diagram illustrating a structure of a display apparatus according to an embodiment of the present disclosure. FIG. 2 is a view illustrating a display apparatus according to an embodiment of the present disclosure.

Referring to FIG. 1, a display apparatus 100 includes a sensor 110, a display unit 120, an input unit 130, and a controller 140. The display apparatus 100 may be realized as a smart TV, but this is only an example. The display apparatus 100 may be realized as various types of apparatuses (e.g., electronic devices) such as a desktop personal computer (PC), a notebook PC, a monitor, and/or the like.

The sensor 110 detects whether a user approaches the display apparatus 100. In detail, the sensor 110 may capture a preset area around the display apparatus 100 by using a camera and, when the user goes into the captured preset area, detect whether the user approaches the display apparatus 100.

The display unit 120 outputs image data under control of the controller 140. In particular, if the user is detected by the sensor 110 when the display apparatus 100 keeps a standby mode, the display unit 120 may display at least one object in an area thereof under control of the controller 140. The at least one object may be a display item for controlling the display apparatus 100.

In particular, the display unit 120 may include a first display unit that displays a general image content and a second display unit that displays an image or an object outside the first display unit. For example, as illustrated in FIG. 2, a first display unit 121 may be realized as a liquid crystal display (LCD) that displays an image, and a second display unit 123 may be realized as a projector display that displays an image outside the LCD.

According to various embodiments of the present disclosure, if the user is detected by the sensor 110 when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in standby mode), then the second display unit 123 may display at least one object. If an object is selected (e.g., in response to selection of the object), then the first display unit 121 may display an image corresponding to the selected object.

The input unit 130 receives a user command for controlling the display apparatus 100. In particular, the input unit 130 may be realized as a hand motion detecting module that detects a hand motion of the user, but this is only example. The input unit 130 may be realized as various types of input devices such as a pointing device, a mouse, a remote controller, and/or the like.

The controller 140 controls an overall operation of the display apparatus 100 according to the user command input through the input unit 130. In particular, if the user is detected through the sensor 110 when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in standby mode), then the controller 140 may control the display unit 120 to activate an area of the display unit 120 in order to display at least one object.

In detail, if the user is detected through the sensor 110 when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in standby mode), then the controller 140 may control the display unit 120 to activate the second display unit 123 in order to display at least one object for controlling the display apparatus 100.

The controller 140 determines whether the detected user is a user registered in the display apparatus 100. In detail, the controller 140 may determine whether a detected user is a user registered in the display apparatus 100 by using a face recognition, an iris recognition, a fingerprint recognition, near field communication (NFC) tagging, and/or the like.

If the detected user is the user registered in the display apparatus 100 (e.g., in response to determining that the detected user is registered with the display apparatus 100), then the controller 140 may control the second display unit 123 to acquire user information corresponding to the detected user stored in the display apparatus 100 and display at least one object based on the acquired user information. The user information may be at least one of preferred channel information, reserved viewing information, content use information using an external apparatus, recommendation content information, and SNS information.

In other words, the display apparatus 100 may store reserved viewing information, content use information using an external apparatus, recommendation content information, and SNS information according to users, and the controller 140 may provide different objects to the detected user. For example, if there is a broadcasting program that is reserved by user A, then the controller 140 may control the second display unit 123 to display an object for viewing the broadcasting program reserved by the user A.

If one of the at least one objects displayed on the second display unit 123 is selected through the input unit 130 (e.g., in response to selection of one of the at least one objects), then the controller 140 may control the display unit 120 according to the selected object. For example, if an object corresponding to providing of a recommendation content is selected from the at least one object displayed on the second display unit 123 through the input unit 130 (e.g., in response to selection of the object corresponding to providing of a recommendation content), then the controller 140 may control the first display unit 121 to display a user interface (UI) that shows the recommendation content for the detected user.

The controller 140 may be realized as one chip, but this is only an example. The controller 140 may be realized as a chip of each of a main controller that controls an overall function of the display apparatus 100 and a sub controller that displays at least one object.

In detail, if the user is detected through the sensor 110 when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in the standby mode), then the sub controller may be activated and may control the second display unit 123 to display at least one object. If one of the at least one object is selected (e.g., in response to selection of one of the at least one object), then the sub controller may be inactivated, and the main controller may be activated. The main controller may control the first display unit 121 to display an image related the selected object.

As described above, the controller 140 may be classified into a sub controller and a main controller, and thus the display apparatus 100 may minimize power for displaying an object in the standby mode.

If an external apparatus is connected to the display apparatus 100 when the display apparatus 100 keeps an activated normal mode (e.g., in response to an external apparatus being connected to the display apparatus 100 when the display apparatus 100 is in an activated normal mode), then the controller 140 may control the second display unit 123 to display an object for controlling the external apparatus. If the object for controlling the external apparatus is selected through the input unit 130 (e.g., in response to selection of the object for controlling the external apparatus), then the controller 140 may control the first display unit 121 to display a UI for controlling the external apparatus.

If the display apparatus 100 stores reserved viewing information about a particular broadcasting program, and a reserved viewing time included in the stored reserved viewing information arrives, then the controller 140 may control the second display unit 123 to display an object that shows reserved viewing. For example, at a reserved viewing time (e.g., a broadcast time associated with the particular broadcasting program associated with the corresponding reserved viewing information), the controller 140 may control the second display unit 123 to display an object that shows the reserved viewing associated with reserved viewing information that includes the reserved viewing time. If the object that shows the reserved viewing is selected through the input unit 130 (e.g., in response to selection of the object that shows the reserved viewing), then the controller 140 may control the first display unit 121 to select and display a reserved broadcasting program.

If a message corresponding to the user detected through the sensor 110 is stored in the display apparatus 100, then the controller 140 may control the second display unit 123 to display an object corresponding to the message. If the object corresponding to the message is selected through the input unit 130 (e.g., in response to selection of the object corresponding to the message), then the controller 140 may control the first display unit 121 to play the message.

Through the display apparatus 100 described above, the user may easily and conveniently perform a function of the display apparatus 100 by using an object displayed in an area of a display unit even when the display apparatus 100 keeps the standby mode.

The display apparatus 100 will now be described in more detail with reference to FIGS. 3 through 8.

FIG. 3 is a block diagram illustrating a detailed structure of the display apparatus according to an embodiment of the present disclosure.

Referring to FIG. 3, the display apparatus 100 includes the sensor 110, the display unit 120, the input unit 130, the controller 140, a broadcasting receiver 150, a communicator 160, an external apparatus input terminal 170, a storage unit 180, and a power supply unit 190.

FIG. 3 illustrates various types of elements of the display apparatus 100 that is realized as an apparatus having various functions such as a content providing function, a user recognizing function, a displaying function, an SNS providing function, and/or the like. Therefore, according to various embodiments of the present disclosure, some of the elements of FIG. 3 may be omitted or changed, or other types of elements may be further added.

The sensor 110 detects whether the user approaches the display apparatus 100. In detail, the sensor 110 may capture a preset area around the display apparatus 100 by using a camera. If the user is detected when capturing the preset area, then the sensor 110 may determine that the user approaches the display apparatus 100.

The determination of the sensor 110 as to whether the user approaches the display apparatus 100 by using the camera is only an example. Therefore, the sensor 110 may determine whether the user approaches the display apparatus 100, by using at least one of an NFC module, an infrared sensor, and an audio sensor.

The broadcasting receiver 150 may receive a broadcasting content from an external broadcasting station in real time. In particular, the broadcasting receiver 150 may select a broadcasting channel selected by the user and receive a broadcasting channel of the selected broadcasting channel.

The communicator 160 communicates with various types of external apparatuses according to various types of communication methods. The communicator 160 may include various types of chips such as a WiFi chip, a Bluetooth chip, an NFC chip, a wireless communication chip, and/or the like. The WiFi chip, the Bluetooth chip, and the NFC chip respectively perform communications by using a WiFi method, a Bluetooth method, and an NFC method. The NFC chip operates according to an NFC method using a band of 13.56 MHz among various radio frequency identification (RFID) frequency bands such as 135 KHz, 13.56 MHz, 433 MHz, 860˜960 MHz, 2.45 GHz, and/or the like. If the WiFi chip or the Bluetooth chip is used, then the communicator 160 may transmit and receive various types of connection information such as subsystem identification (SSID), a session key, and/or the like to perform communication connections by using the various types of connection information in order to transmit and receive various types of information. The wireless communication chip may perform communication according to various types of communication standards such as IEEE, 3rd Generation (3G), 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), and/or the like.

The display unit 120 controls an overall operation of the display apparatus 100 under control of the controller 140. In particular, the display unit 120 includes the first display unit 121 that displays an image received from the broadcasting receiver 150, the communicator 160, and the external apparatus input terminal 170, and the second display unit 123 that displays an object for controlling the display apparatus 100 outside the display unit 121.

Referring to FIG. 2, the first display unit 121 may be realized as an LCD, and the second display unit 123 may be realized as a projector display, but this is only an example. Therefore, the first display unit 121 may be realized as various types of displays such as an organic light-emitting diode (OLED), a plasma display panel (PDP), and/or the like, and the second display unit 123 may be realized as various types of displays such as a transparent display, and/or the like disposed outside the display unit 121.

The external apparatus input terminal 170 is connected to an external apparatus. For example, the external apparatus input terminal 170 may be connected to an external apparatus to receive an image content from the external apparatus. The external apparatus input terminal 170 may transmit a user command input through the input unit 130 to the external apparatus.

The storage unit 180 stores various types of modules for driving the display apparatus 100. For example, the storage unit 180 may store software including a base module, a detecting module, a communication module, a presentation module, a web browser module, a service module, and/or the like. The base module processes a signal transmitted from each hardware included in the display apparatus 100 and transmits the processed signal to an upper layer module. The detecting module may collect information from various types of sensors, analyze and manage the collected information, and include a face recognition module, a voice recognition module, a motion recognition module, an NFC recognition module, and/or the like. The presentation module constitutes a display screen and may include a multimedia module that plays and outputs a multimedia content and a UI rendering module that processes a UI and a graphic. The communication module communicates with the external apparatus. The web browser module performs web browsing to access a web server. The service module includes various types of applications for providing various services.

As described above, the storage unit 180 may include various types of program modules, and some of the various types of program modules may be omitted, changed, or added according to a type and a characteristic of the display apparatus 100. For example, if the display apparatus 100 is realized as a smartphone, the base module may further include a position determination module that determines a global positioning system (GPS)-based position, and the detecting module may further include a detecting module that detects a motion of the user.

The storage unit 180 may store user information according to users. The user information may include at least one of preferred channel information, reserved viewing information, content use information using an external apparatus, recommendation information, and/or the like. In detail, the controller 140 may periodically check a reservation function execution to store reserved viewing information (e.g., a broadcasting time, a broadcasting program image, reserver information, and/or the like) of the user in the storage unit 180. If the external apparatus is connected to the display apparatus 100, the controller 140 may store file information and play time information of a content provided by the external apparatus, and information about the connected external information in the storage unit 180. The controller 140 may analyze a content using pattern of the user to store information about a recommendation content of the user (e.g., a recommendation content genre, a recommendation content-related image, information about an object to be recommended, and/or the like) in the storage unit 180.

The storage unit 180 may store a message written by the user.

The power supply unit 190 supplies power to elements of the display apparatus 100. In particular, when the display apparatus 100 keeps the standby mode, the power supply unit 190 may supply power only to the sensor 110 not to the other elements. If the user is detected through the sensor 110, then the power supply unit 190 may supply power to a sub controller 141 to activate the sub controller 141. In addition, when the display apparatus 100 normally operates in a normal mode, the power supply unit 190 may supply power to all elements of the display apparatus 100. According to various embodiments of the present disclosure, the display apparatus 100 may only supply power to elements required to detect a user when the display apparatus 100 is in a standby mode. According to various embodiments of the present disclosure, when the display apparatus 100 is in a standby mode, the display apparatus 100 may supply power only to essential elements such as elements required to detect a user.

The input unit 130 receives a user command for controlling the display apparatus 100. In particular, the input unit 130 may be realized as a motion input unit that inputs a user command by using a hand gesture of the user.

In particular, the input unit 130 may divide an image (e.g., consecutive frames) corresponding to a motion of the user input through the camera into a background area and a hand area (e.g., spreading fingers or closing fists) by using a motion recognition module and recognize consecutive motions of a hand.

In detail, if a motion of the user is captured, then the input unit 130 stores the received image in the frame unit and detects an object of the motion of the user (e.g., a hand of the user) by using the stored frames. The input unit 130 detects at least one of a shape, a color, and a motion of an object included in a frame to detect the object. The input unit 130 may trace a motion of the detected object by using positions of objects included in a plurality of frames.

The input unit 130 determines a motion according to the shape and the motion of the traced object. For example, the input unit 130 determines a motion of the user by using at least one of a change of a shape of an object, a speed of the object, a position of the object, a direction of the object, and/or the like. The motion of the user includes grabbing that corresponds to a motion of grabbing a hand, a pointing move that corresponds to a motion of moving a marked cursor with a hand, a slapping that corresponds to a motion of moving a hand in one direction at a preset speed or more, a shaking that corresponds to a motion of shaking the hand to the left and/or right or upwards and downwards, a rotating that corresponds to a motion of rotating the hand, and/or the like. Various embodiments of the present disclosure may be applied to other motions besides motions described in the above embodiment. For example, a spreading motion, and/or the like of spreading a hand may be further included.

The input unit 130 determines whether an object gets out of a determined area (e.g., a square of 40 cm×40 cm) within a determined time (e.g., 800 ms) to determine whether a motion of the user is a pointing move or slapping. If the object does not get out of (e.g., does not exit) the determined area within the determined time, then the input unit 130 may determine that the motion of the user is the pointing move. If the object gets out of (e.g., exits) the determined area within the determined time, then the input unit 130 may determine that the motion of the user corresponds to a slapping. As another example, if the speed of the object is determined to be slower than or equal to a preset speed (e.g., 30 cm/s), then the input unit 130 determines that the motion of the user corresponds to the pointing move. If the speed of the object is determined to exceed the preset speed, then the input unit 130 determines that the motion of the user corresponds to a slapping. As described above, the input unit 130 performs a function or a task of the display apparatus 100 by using the recognized hand gesture.

However, inputting of the user command through the input unit 130 by using the hand gesture of the user is only an example. Therefore, the user command may be input by using various types of input devices such as a pointing device, a voice recognizing device, a mouse, a touch panel, a remote controller, and/or the like.

The controller 140 controls an overall function of the display apparatus 100 according to the user command input through the input unit 130. In particular, the controller 140 includes the sub controller 141 and a main controller 143 as illustrated in FIG. 3

If the user is detected when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in the standby mode), then the sub controller 141 may be supplied with power from the power supply unit 190 to be activated and control the second display unit 123 to display at least one object for controlling the display apparatus 100. If the display apparatus 100 is changed from the standby mode into the normal mode (e.g., in response to the display apparatus 100 being changed from the standby mode into the normal mode), then the main controller 143 may be supplied with power from the power supply unit 190 to be activated and control an overall operation of the display apparatus 100. If the main controller 143 is activated (e.g., in response to activation of the main controller 143), then the sub controller 141 may be changed into an inactivation state. Detailed operations of the sub controller 141 and the main controller 143 will now be described in detail with reference to FIGS. 4A through 8.

The display apparatus 100 keeps the standby mode. The standby mode refers to a mode in which power is not supplied to other elements of the display apparatus 100 except the sensor 110.

If the user is detected through the sensor 110 when the display apparatus 100 keeps the standby mode (e.g., in response to detecting the user when the display apparatus 100 is in the standby mode), then the power supply unit 190 supplies power to the sub controller 141 to activate the sub controller 141.

The sub controller 141 that is activated may control the second display unit 123 to display a display item 410 corresponding to the detected user as illustrated in FIG. 4A. The display item 410 may be a shape of a person and may move to correspond to a motion of the user captured by the sensor 110. However, this is only an example, and the display item 410 may be realized as another type of indicator. For example, if the person is detected (e.g., in response to detecting the person), then the sub controller 141 may display a text type of display item or an icon type of display item and output a voice that notifies that the person is detected.

The sub controller 141 may output an indicator to distinguish a case according to which a plurality of persons is detected from a case according to which one person is detected. For example, the sub controller 141 may display a plurality of person shapes of display items and display a text notifying that a plurality of persons are detected or output a voice notifying that the plurality of persons are detected.

The sub controller 141 may determine whether the detected user is a user stored in the storage unit 180. In detail, the sub controller 141 may determine that the detected user is the user stored in the storage unit 180, by using various recognition methods such as a face recognition, a fingerprint recognition, an iris recognition, and/or the like.

If the detected user is determined to be the user stored in the storage unit 180 (e.g., in response to determining that the detected user corresponds to the user stored in the storage unit 180 or otherwise registered with the display apparatus 100), then the sub controller 141 may search the storage unit 180 for user information corresponding to the detected user. The sub controller 141 may also acquire user information corresponding to the detected user. The user information may include at least one of preferred channel information, reserved viewing information, content use information using an external apparatus, recommendation content information, SNS information, and/or the like.

In addition, the sub controller 141 may control the second display unit 123 to display at least one object for controlling the function of the display apparatus 100 based on the acquired user information. In detail, if user A is detected, then the sub controller 141 may acquire SNS information, preferred channel information, digital versatile disc (DVD) play information, recommendation content information, and/or the like of the user A. The SNS information may be acquired from an SNS server through the communicator 160 and may include an SNS update message, an SNS update time, and/or the like.

FIGS. 4A, 4B, 4C, 5A, 5B, 5C, 5D, 5E, 6A, 6B, 7A, 7B, and 8 are views illustrating an object that is displayed on a second display unit according to an embodiment of the present disclosure.

Referring to FIGS. 4A, 4B, and 4C, the controller 140 (e.g., the sub controller 141) may control the second display unit 123 to display a first object for providing an SNS service, a second object 430 for providing a content (e.g., TV content) viewing service, a third object 440 for providing a media (e.g., DVD play) service, a fourth object 450 for providing a content recommendation service, and/or the like. For example, the sub controller 141 may control the second display unit 123 to display a first object 420 for performing an SNS service based on acquired SNS information, a second object 430 for immediately selecting a preferred channel based on preferred channel information, a third object 440 for continuously playing a content that is previously played based on DVD play information, and a fourth object 450 for providing a recommendation content UI based on recommendation content information.

If one of at least one displayed object is selected through the input unit 130 (e.g., in response to selection of one of the at least one displayed object), then the sub controller 141 controls the power supply unit 190 to supply power to the main controller 143, and the main controller 143 is activated. A mode of the display apparatus 100 may be changed from the standby mode into the normal mode.

The main controller 143 may perform a function of the display apparatus 100 corresponding to the selected object. In detail, as illustrated in FIG. 4B, if a user command to select the second object 430 (e.g., a command to allow the user to perform grabbing when a pointer 460 is positioned on the second object 430) is input (e.g., in response to selection of the second object 430), then the main controller 143 may control the broadcasting receiver 150 and the first display unit 121 to display a broadcasting program of channel 11 that is a preferred channel of user A as illustrated in FIG. 4C.

According to various embodiments of the present disclosure, if a user command to select the first object 420 is input (e.g., in response to selection of the first object 420), then the main controller 143 may control the communicator 160 and the first display unit 121 to display a UI including a message updated in an SNS account of the user A.

According to various embodiments of the present disclosure, if a user command to select the third object 440 is input (e.g., in response to selection of the third object 440), then the main controller 143 may control the external apparatus input terminal 170 and the first display unit 121 to continuously play a content that is previously played through a DVD device.

According to various embodiments of the present disclosure, if a user command to select the fourth object 450 is input (e.g., in response to selection of the fourth object 450), then the main controller 143 may control the first display unit 121 to display a UI including a recommendation content of the user A.

After an object is selected, at least one object displayed on the second display unit 123 may be continuously displayed, but this is only an example. Therefore, the main controller 143 may control the second display unit 123 to remove at least one object from a display screen.

As described above, when the display apparatus 100 keeps the standby mode, an object for controlling the display apparatus 100 may be displayed to the user through the second display unit 123. Therefore, the user may further easily and conveniently control the function of the display apparatus 100.

If an external apparatus is connected to the display apparatus 100 when the display apparatus 100 keeps the normal mode (e.g., in response to an external apparatus being connected to the display apparatus 100 when the display apparatus 100 is in the normal mode), then the controller 140 may control the second display unit 123 to display an object for controlling the external apparatus on the second display unit 123.

Referring to FIG. 5A, the display apparatus 100 may control the first display unit 121 to display a broadcasting program. If a smartphone is connected to the display apparatus 100 when the display apparatus 100 keeps the normal mode, the main controller 143 may determine whether the connected smartphone newly stores a content.

Referring to FIG. 5B, if the smartphone newly stores the content (e.g., in response to the main controller 143 determining that the connected smartphone newly stores the content), then the main controller 143 may control the second display unit 123 to display a fifth object 510 showing information about the content newly stored in the smartphone.

Referring to FIG. 5C, if a user command is not input for a preset time (e.g., 1 minute) after an object is displayed, then the main controller 143 may control the second display unit 123 to display a sixth object 520 smaller than the fifth object 510. In other words, if there is no input of the user after time elapses, then the main controller 143 may reduce a size of an object so as not to interrupt viewing of an image that is currently output from the first display unit 121.

Referring to FIGS. 5C and 5D, if a user command to select the sixth object 520 (e.g., a command, and/or the like to allow the user to perform grabbing when a pointer 530 is displayed on the sixth object 520) is input when the sixth object 520 is displayed (e.g., in response to selection of the sixth object 520), then the controller 140 may control the first display unit 121 to display a UI for playing the content newly stored in the smartphone as illustrated in FIG. 5D.

As described above, an object for playing a content of an external apparatus that is newly connected may be displayed on the second display unit 123. Therefore, the user may display a UI for playing a content stored in the external apparatus without being interrupted in viewing of a content that is currently viewed.

In the above-described embodiment of the present disclosure, the main controller 143 displays the fifth object 510 on top of the second display unit 123, but this is only an example.

Referring to FIG. 5E, the fifth object 510 may be displayed on bottom of the second display unit 123.

If reserved viewing information is stored in the storage unit 180, and a reserved viewing time included in the stored reserved viewing information arrives, then the controller 140 may control the second display unit 123 to display an object showing reserved viewing on the second display unit 123.

Referring to FIGS. 6A and 6B, if a reserved viewing time of pre-stored program A of channel 11 arrives when the display apparatus 100 keeps the standby mode, then the sub controller 141 may be activated and control the second display unit 123 to display a seventh object 610 showing reserved viewing. A UI showing reserved viewing may include at least one of channel information, program information, a program thumbnail image, and/or the like. If a user command to select the seventh object 610 showing the reserved viewing (e.g., a command, and/or the like to allow the user to perform grabbing when a pointer 620 is displayed on the seventh object 610) is input (e.g., in response to selection of the seventh object 610), then the main controller 143 may be activated, may control the broadcasting receiver 150 to select channel 11 corresponding to the selected seventh object 610, and may control the display unit 121 to display the program A of the channel 11.

In the above-described embodiment of the present disclosure, if a reserved viewing time arrives, then the sub controller 141 displays an object showing reserved viewing, but this is only an example. Therefore, the sub controller 141 may display an object showing reserved viewing before a preset time (e.g., 5 minutes) of the reserved viewing time. In addition, in the above-described embodiment of the present disclosure, if the reserved viewing time arrives in the standby mode, then the sub controller 141 displays an object showing reserved viewing, but this is only an example. Therefore, if the reserved viewing time arrives in the normal mode, then the main controller 143 may display the object showing the reserved viewing.

According to various embodiments of the present disclosure, the controller 140 may determine whether a message corresponding to the detected user is stored in the storage unit 180. If the message corresponding to the detected user is stored in the storage unit 180 (e.g., in response to receipt of the message corresponding to the detected user and/or in response to determining that currently displayed content has a message associated therewith stored in the storage unit 180), then the controller 140 may control the second display unit 123 to display an object corresponding to the message. If the object corresponding to the message is selected through the input unit 130, then the controller 140 may control the first display unit 121 to play the message.

Referring to FIGS. 7A and 7B, if the user is detected through the sensor 110, then the sub controller 141 may be activated and may determine whether the detected user is a user stored in the storage unit 180. If the detected user is determined to correspond to the user stored in the storage unit 180, then the sub controller 141 may determine whether there is a message left to the determined user (e.g., the user registered with the display apparatus 100). The message may be one of a voice message, a text message, a moving picture message, and the like. As illustrated in FIG. 71, if there is the message left to the user, then the sub controller 141 may control the second display unit 123 to display an eighth object 710 corresponding to the message. One of a type of message, information about a user leaving the message, and message play information may be displayed in the eighth object 710. If a user command to select the eighth object 710 corresponding to the message (e.g., a command, and/or the like to allow the user to perform grabbing when a pointer 720 is displayed on the eighth object 710) is input (e.g., in response to selection of the eight object 710), then the main controller 143 may be activated and may control the first display unit 121 to play the message corresponding to the selected eighth object 710 as illustrated in FIG. 7B.

Referring to FIG. 8, the controller 140 may control the second display unit 123 to display a background screen on the second display unit 123. For example, if weather information is received through the communicator 160 in real time, the controller 140 may control the second display unit 123 to display a background screen corresponding to the received weather information as illustrated in FIG. 8. As another example, if an anniversary stored in the storage unit 180 arrives, the controller 140 may control the second display unit 123 to display a background screen corresponding to the anniversary. As another example, if the user designates a particular background screen, the controller 140 may control the second display unit 123 to display the background screen designated by the user. According to various embodiments of the present disclosure, the controller 140 may control the second display unit 123 to display a background screen on the second display unit 123 that is configurable by a user. The background screen may provide contextual information and/or information relating to the user of the display apparatus 100.

As illustrated in FIG. 8, the second display unit 123 may display a background screen that include one or more of a first object 810 for providing a SNS service, a second object 820 for providing a content service, a third object 830 for providing a media service, a fourth object 840 for providing a content recommendation service, a fifth object 850 for providing a weather service, and/or the like.

Through the display apparatus 100 as described above, the user may further conveniently and intuitively control the display apparatus 100 by using an object in the standby mode. In addition, the display apparatus 100 may display an object by using the second display unit 123 positioned outside the first display unit 121 on which a general content is played. Therefore, the user may control various functions of the display apparatus 100 without being interrupted in viewing of the general content. In addition, the display apparatus 100 may provide an object for controlling the display apparatus 100 to each user. Therefore, the user may be provided with a user-customized service.

A method of controlling the display apparatus 100 will now be described with reference to FIG. 9.

FIG. 9 is a flowchart illustrating a method of controlling a display apparatus according to an embodiment of the present disclosure.

At operation S910, the display apparatus 100 keeps a standby mode. The standby mode refers to a mode in which power is supplied only to the sensor 110 for detecting a user not to the other elements. The standby mode may refer to a mode in which power is not supplied to elements that are not otherwise required to detect a user (e.g., whether a user is present in the environment or preset area around the display apparatus 100).

At operation S920, when the display apparatus 100 keeps the standby mode, the display apparatus 100 determines whether the user is detected. In detail, the display apparatus 100 may capture a preset area around the display apparatus 100. In addition, if the user is detected in the preset area, the display apparatus 100 may determine that the user is detected.

If the display apparatus 100 determines that the user is not detected at operation S920, then the display apparatus may return to operation S910.

In contrast, if the display apparatus 100 determines that the user is detected at operation S920, then the display apparatus may proceed to operation S930 at which the display apparatus 100 activates an area of a display unit to display at least one object. In particular, the display apparatus 100 may display at least one object for controlling a function of the display apparatus 100 on the second display unit 123 disposed outside the first display unit 121.

At operation S940, the display apparatus 100 determines whether one or more of the at least one object is selected. The user may select the object through a hand gesture input, and/or the like.

If the display apparatus 100 determines that the object is not selected at operation S940, then the display apparatus 100 may end the process for controlling the display apparatus 100.

In contrast, if the display apparatus 100 determines that one or more of the at least one object is selected at operation S940, then the display apparatus 100 may proceed to operation S950 at which the display apparatus 100 may control the display apparatus 100 according to the selected object. For example, if one of the at least one object is selected, the display apparatus 100 may display an image corresponding to the selected object on the first display unit 121.

Through the above-described method of controlling the display apparatus 100, even when the display apparatus 100 keeps the standby mode, the user may easily and conveniently perform a function of the display apparatus 100 by using an object displayed in an area of the display unit.
